Abstract

In this age of universal electronic connectivity, there is no time at which security does not matter. With the increase in usage of transmission of digital images over the network, there is need of more secure systems. The main aim of this paper is to achieve two main principles of security i.e. authenticity and confidentiality, particularly for transmission of images over a network. Authenticity ensures that only the intended receiver is able to receive the message and confidentiality ensures that the message is confidential. For achieving these two principles, there are lots of mechanisms available, e.g. the most common practices for achieving authenticity are passwords, access control etc. and for achieving confidentiality, there are lots of symmetric and asymmetric encryption methods available. In this paper, a two-level security mechanism has been presented. This two level security ensures authenticity at one level and confidentiality at another level. For achieving first level of security, the image to be send is hidden behind another image using Stenographic methods and for achieving second level of security, the image would be encrypted using 2D Cellular Automata (CA) rules. If one level of security is broken, then the other level would provide security.
